There are plenty of reasons to be excited about "Jurassic World," the forthcoming fourth "Jurassic Park" movie being directed by Colin Trevorrow, but only one that really matters: The incredible sexiness of leading man Chris Pratt. Sure, he looks great as Star-Lord in Marvel's "Guardians of the Galaxy," but the first still of Pratt as Owen in "Jurassic World" (released on June 12 by
AV Club) proves that he is a man we all should be drooling over.

Pratt underwent a pretty radical body transformation when preparing for his role in "Guardians." Previously known best as chubby goof Andy Dwyer on
"Parks and Recreation," Pratt turned fat into muscle and finally flaunted a very svelte new look on Instagram.

"I love eating food and drinking beer and having fun with my life. I was also kind of depressed a little bit when I was fat," he said at
Comic-Con 2013 of losing weight and toning up. "All it takes is like six months really.' Six months flies by whether you're working out every day or whether you're not, so if you feel compelled to do something about it, take some action and get in shape, do it. You can do it."

Clearly that new mentality is paying off, judging by the "Jurassic World" photo. Though there also are images showing stars Bryce Dallas Howard, Ty Simpkins and Nick Robinson, it's Pratt's photo that we're totally obsessed with. In honor of Pratt's year of sexiness, here's how Andy Dwyer would react to seeing dinosaur-encountering Owen for the first time.
